SIGNALING DEVICE.

Specification of Letters Patent.

ratentedapr. 23, 1era.y

Application filed May 11,1912. Serial No. 696,697.

To alljteftom tr/tay concern.

Be it known that I, MARK SLMoRsE, c1t1- zen of the United States, residmg at Oakland, in the county ofV Alameda and State of California, have invented certain new and useful Improvements 1nk Signaling Devices,

ofv which the following is a specification.

My present inventionrelates `to signal saystenis and instrumentality appertalnmg thereto,andis articularly adapted for use 1n connection with railroads where it is usu-V ally desirable that the signal' device proper be lremotefrom the ii'istrumentality which setsthe signal into action.`

The principal object of, my invention isv toprovide instrumentality disposed inelectric conductingmeans which is setinto operation to` complete a circuit therethrough, due

to the vibrations ofsome portion of the.

stationary stock, such as'the rails, of a railway,lresu1ting from the passage of'some of the rolling stock thereby, the circuit thus completed 'setting into operation suitable signal mechanism.'

Further objects'of my-invention are, to provide a simple .andecient device for completing the electric circuit, and to` render the device adjustable so .as to be sensitive according to the vibratory qualities of the element to which itis connected.

In the drawings, forming a part' of this specification: Figure 1` is a view partly in section and partly in elevation, `showinglthe application ofitlie device embodying my invention applied to a rail. Fig. 2. is atransverse `vertical sectional view through the casing of the" device embodyingr my invention.

Fig.` 3 is adiagrammatic -vicw showing the ap lication of thc device to a signal system. imllarv characters refer to similar parts throughout the vlews.

Generally speaking, 1 designates a.. rail of a railway, 2 the circui'teontrol device, and

3 the arm for rigidly securingthc said device to said rail.

lVhile I have shown the device as attached v to a rail and will hereinafter describe ,it as beingso attached, it is to beundcrstood that1tl1e said device may be attached to or supported byany other` element,` such as trolley wire support, `orrail tie, which is in proximity to thev` place where the action of 'moving rolling stock is to set the signal ersignals into motion, and which is vxbrated by the movement of such stock. .The said arm 11. Theelcctro-magnet lerably provided with standards 12, 13 and V19, and the other tro-magnet trame 8, of non-magnetic niaterial; electro-magnets S); for said magnets; and a vibratablc Contact frame Sis pref- 14,` the former two supporting the electromagnets, while-the-latterk carries an adjustable screw 15; The standard wlth arms16, which pivotally support the armature holder'lO, and arms 17 and'I 18, the latter of which earriesinsulated therefrom a an armature 10 13 is provided contact 19 for;coperation` with the saidl vibratablearm 11. This latter element is carried in an insulated manner by armature l holder 10 and projects between thecontaet 119 andarm 17, normally resting against the atter.

ing through anaperture 21 in standard -13,

which is adapted-to receive a weight 22. By moving this weight farther away from the lpivotal point ofarm 10,.mere tension' isv The, support 10 has an arm 20 passplacedfuponvibratable arm1'1 against arm 17,' or`by movingit towardthe said pivotal point, the tension is reduced, In other words, from the pivotal point ci` the-.arm 10the nnnimum amplitude of vibration to which the arm 1l will respond" is aezordingly'increased, and by this means adjustment' .ofi

the relay to the minimum amount ofvibration to which it is desired tosubject the reby` moving the weight 22 farther` lay to foroperation is obtained.'4 The vi'bratable arm 11,is, by conductor`-23, connected withA the coils of electro-magnets 9. As `a.

practical' embodiment of my with particular reference to drawing, an electric invention, and Fig. 3 of 'the .generator 24C" is vprovided, one poleof which, b v conductor 26,

being operatively connected with contact 4 vpele, being operatively. connected by conductoru25 with theeleetro magnetsr 9.; Operatively' connected with eithervconductor, inl the drawing-that designated 26, I. dispose a-.switelrdeviee 27, of.

any suitable'type, andan electro-magnet28. This electromagnet 28, when energized, is adapted to draw an armature'29 to contact or complete a circuit througha contact'BO.

This contact 30 and armature 29 fare, by conrespectively. connected ductors 31 and 32, with an electric 'generator 33 an n the cir- 'cuit is disposed a signal device 34. oi. the audible type, although it is to be understood that a visional signal oran audible'signal, other than that showm of any suitable type, may beruscd without departing from the spirit of my invention. y

.W'ith particular reference to the arm 3, as

shown in the drawing, it includes a hook to engage over one llange of the rai-l l, a .strap 36 being secured by nut and bolt 37 'and 38, respectively. over the other flange in connection with the arm 3. By this arrangement the. vibration imparted to the' rail l by-the rolling stock is transmitted to the device 2, and more particularly to actuate arm 11.

The operation of the device is as follows: When rolling stock passes over the rail' or in proximity to the element to which the circuit control device is attached or supported, the arm l1 is' vibrated and as soon es amplitude of vibration is suicient to Contact vthe said arm with contact 19, a circuit is completed through electro-magnets 9 which immediately Adraws the armature 10 towardit and so retains it with the said arm lilin engagement with contact 19. Inasmuch as with this position of parts, a continuouscir cuit is formedfthrough the' electric-maggie@- 9, the said armature l() is rigidly held under influence thereof and likewise, the arm il and Contact 19 are in engagement. The completed circuit through. electro-magnet QSiaetuates armature 29 and a circuit is completed :throughsignal device 34, to actuate it. The signal 34 remains active or set` until the switch 27 is opened. Switch 27 is of `the normally closed type and preferahlylocated adjacent to the signal 34 lso that such signal may readily be rendered inoperative after each passage ofthe rolling stock.
